As typical II–VI ternary alloyed chalcogenides, CdSeS nanostructures have attracted intensive worldwide attention due to their excellent tunable optical properties based on quantum confinement effect and optical nonlinear phenomenon. Because CdSeS-based nanostructures have presented a great potential for applications in biomedicine and optoelectronic devices, different synthesis methods have been proposed to prepare CdSeS-based nanostructures with divergent optical properties to meet the needs of those applications, such as fluorescent labeling,in vivoimaging, waveguides, and solar cell. In this review, the tricks, advantages, and disadvantages of all these synthesis methods were discussed, including hot-injection synthesis, one-pot noninjection synthesis, microwave irradiation, solvothermal synthesis, template-assisted electrodeposition, thermal evaporation, and pulsed laser deposition. Special emphasis was put on those methods that are safe, economic, environment-friendly, and suitable for large-scale production of alloyed CdSeS nanostructures with high photoluminescence, high stability, and low/no cytotoxicity.

A novel CdS quantum dots (QDs) were successfully synthesized in aqueous phase using poly (acrylic acid) grafted onto starch (starch-g-PAA). UV-vis spectroscopy, fluorescence spectroscopy, transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR) techniques proved that the prepared starch-capped CdS QDs are composed of a CdS core and a polymeric shell with homogeneous size distributions. In order to study its biological behavior, multi-spectroscopic techniques were adopted to investigate their conjugation with human serum albumin (HSA) and bovine serum albumin (BSA) proteins. The recorded UV-vis spectra, cyclic voltammetry (CV) analysis, and the calculated rate of HSA and BSA fluorescence quenching by the QDs demonstrated that the interaction between them leads to the formation of QDs-HSA and QDs-BSA complexes. Moreover, FT-IR spectra showed the conformational changes of the protein in the presence of obtained QDs, indicating the presence of interaction between modified QDs and proteins.
